Apple Officially Reveals How Long Siri Keeps Your Data

Apple has finally revealed how long Siri stores your data. The company told that questions asked through the digital assistant stays on its servers for up to two years. The response came after Wired raised some concerns about Apple's dodgy privacy policy for Siri. Apple spokeswoman Trudy Muller called the tech blog to explain. Here's what Wired has learned.


"Whenever you speak into Apple’s voice activated personal digital assistant, it ships it off to Apple’s data farm for analysis. Apple generates a random numbers to represent the user and it associates the voice files with that number. This number — not your Apple user ID or email address — represents you as far as Siri’s back-end voice analysis system is concerned."

"Once the voice recording is six months old, Apple 'disassociates' your user number from the clip, deleting the number from the voice file. But it keeps these disassociated files for up to 18 more months for testing and product improvement purposes."

Muller says users can delete both identifiers and any stored data by switching Siri off.

"Apple may keep anonymized Siri data for up to two years,” Muller says “If a user turns Siri off, both identifiers are deleted immediately along with any associated data.”

Nicole Ozer, a lawyer for the American Civil Liberties Union, is urging Apple to add this information to its official Siri page on

“There is no good reason for Apple to not include information about privacy practices on their Siri FAQ page,” Ozer said in an email message to

Ozer also warns Siri users to think before they speak to the digital assistant.

"What you say to Siri could reveal sensitive things about you, your family, or business,” said Ozer. “Siri works for Apple, so make a note to yourself to really think before you speak.”
